I wrote a parser library based on (slightly extended) Pratt parsing. It's a nice, different location in the design space of parsers. Very declarative, and it allows having great error messages out of the box. https://github.

Pretty lost yeah, but you're asking questions which is better than 90% of the people who are lost. Some very brief answers: They're called qubits; a cubit is a length about 50cm. Pronounced the same though. Quantum computers are n

That's not actually the technique the authors are using. Catching 100 fish would be analogous to "sample 100 YouTube videos at random", but they don't have a direct method of doing so. Instead, they're guessing pos

Some disciplines have started moving to Arxiv. And all the major programming languages conferences (PLDI, POPL, ICFP, more) switched to PACMPL, which is open acess and I expect is cheaper but am not sure how to check. I don't know much

Don't conflate peer review with paid journals, they're very different things. The money received by paid journals doesn't go to the reviewers. The reviewers are mostly professors who have their own funding. I reviewed a paper

Yeah, I feel like PhD committee members often have the opposite problem: you want them to read the thing and suggest improvements, but they're too busy to give more than a skim. A duck would just distract them.

If the voice was chosen specifically to sound like Morgan Freeman, for the purpose of making listeners think it's Morgan Freeman when they hear it, it seems reasonable for it to run afoul of Morgan Freeman's right to publicity.

Sure, call it "reasonable hypocrisy", so long as we don't castigate people doing it. How about wanting to legally abolish tips, because it's unfair and leads to subminimum wages for workers? Must you refuse to tip a wait

There are many cases where you can replace a call to `.iter()` in your Rust code to a call to `.par_iter()` from `rayon`. Those cases are trivial, and it's great.
